An open wound on the foot is called a foot ulcer. It may be either a small red depression that affects only the surface of the skin, or it may also be very deep. A deep ulcer on the foot may spread across the entire thickness of the skin including bones, tendons, and other deep structures. Diabetic patients and people with poor circulation are more prone to develop foot ulcers.
What are diabetic foot ulcers?
Foot ulcers are a frequent cause of poorly regulated diabetes, developed as a result of the breakdown of skin tissue and exposure of the layers below. They are most prevalent under the balls of your feet and big toes and can impact your legs down to the bones.
Such ulcers may cause the skin to erode away, most likely due to weakened nerves in the feet caused by diabetes. Damaged nerves may also make it more difficult for you to experience discomfort or other signs of ulcers or even develop infections. This can prevent you from treating minor wounds until they become ulcers.
All diabetic patients can develop foot ulcers, however, it can be prevented by taking proper care. Treatment for such foot ulcers varies from cause to cause. You must discuss any foot discomfort with your doctor to make sure that this is not a serious issue, as untreated ulcers may lead to amputation if ignored.
Symptoms
Symptoms of diabetic foot ulcers are not always apparent. You may not even display signs of ulcers until the ulcer is infected. Consult your doctor if you experience any irritation, pain, or any new sensation especially in your foot. Some of the symptoms are mentioned below:
Diagnosis
The doctor will assess your blood sugar level especially if you are a diabetic. He/she may evaluate the seriousness of the ulcer by assessing how deep it is, if there is an infection present, if the infection has spread to surrounding areas, your overall health condition, etc.
Certain tests may also be performed to better understand the severity of the ulcer. This may include X-rays, blood tests, bacterial cultures, bone scans, etc.
Causes
Prevention
By taking certain measures, you can reduce the risk of forming ulcers.
Treatment
Typical foot ulcer wound treatment is debridement. This means a doctor cleans and removes all infected and dead tissue, debris, and any residual material from the respective area. The removal of this tissue activates the body’s own healing mechanism. The wound is then covered with a dressing which needs to be changed regularly.
You must also “offload” the affected portion of your foot. You may wear a cast or a surgical shoe to keep the weight off the wound until it heals.
In case the ulcer does not heal in few weeks, or if there is a bone infection, your therapist may recommend more advanced treatment options such as surgery or hyperbolic oxygen therapy (this includes breathing pure oxygen in a unique room to help the body recover).
Antibiotics may be prescribed in case there are any chances of an infection. In extreme cases, if the tissue dies, the doctor may need to amputate that particular part of your body.

When to see a doctor?
You must consult your doctor immediately if you notice any discoloration, discomfort, pain, or numbness surrounding the area of soreness. If left untreated, it may cause infection and spread to other parts of the feet or legs. In such cases, ulcers can sometimes be treated either by amputation, surgery, or by replacing the skin with synthetic skin substitutes.
Conclusion
Anyone with diabetes is prone to develop foot ulcers. It is an open wound or sore usually at the bottom area of the feet. It forms due to various factors like poor circulation, irritation, and injuries. At times diabetic patients lose the ability to experience pain in their feet due to nerve damage and may not be aware of the issue. Talk to your doctor if you notice any symptoms.
Treatment of such ulcers depends on the severity. If detected early, the foot ulcers can be treated. See your doctor immediately if you develop a sore foot, as the risk of infection rises the longer you wait. Undiagnosed infections may involve amputation.
During the time when your foot ulcers heal, offload your feet, and follow the medication as advised by the doctor. It might take a few weeks to heal. In case your blood sugar level is high, it may even take longer. Following a strict diet, a healthy lifestyle, and taking the pressure off your feet is the most efficient way to heal your foot ulcers. When the ulcer is healed, regular preventive treatment may help you avoid the ulcer from ever recurring.
